% Claims.

This invention relates to slug casting machines, such as linotypemachines of the general organization represented in United StatesLetters Patent No. 436,532 to O. Mergenthaler, wherein cir- 5; :culatingmatrices are released from a magazine in the order in which theircharacters are to appear in print, and then composed in line togetherwith spacers, the composed line transferred to the face of a mold, themold filled with molten 10. metal to form a slug or linotype against thematrices which produce the type characters thereon, and the matrices andspacers thereafter returned through distributing mechanism to themagazines from which they started. More particularly, it relates tocertain improvements which adapt these machines, when so desired, tocast successively and automatically a plurality of duplicate slugs fromeach composed line.

. In the preferred embodiment illustrated (although it, is notessential), the improvements have been worked out in the nature of anattachment which can be applied to almost any of the commercial machineswith little or no alteration. Specifically, the equipment consists of astar wheel adapted to be rotated periodically by the movement of thepump actuating lever (means being provided for connecting anddisconnecting the star wheel to and from the pump lever to render theattachment operative or inoperative as desired), and two main trains ofconnections leading therefrom and actuated thereby, one of which trainsrenders the automatic clutch control dog operative and inoperativeduring alternate cycles of operation of the machine, and the other ofwhich trains prevents the removal of the composed line from the firstelevator until the last duplicate slug has been cast therefrom, and alsoprevents the delivery to the first elevator of a second composed lineuntil the first line has been removed therefrom.

' The invention also contemplates an improved galley, which is dividedinto a plurality of compartments adapted to receive and hold theduplicate slugs in separate columns; and associated with the galley is aguide controlled by the first elevator vto direct the slugs into theirproper compartments.

The exact construction and mode of operation of the parts will bebestunderstood from the detailed description to follow.

In the accompanying drawings, the invention is shown merely by way ofexample and in preferred form, but obviously many variations andmodifications may bemade thereinwhich will ssj-still be comprised withinits spirit. :It is to bein line in the assembler B. The assembler is.then understood, therefore, that the invention is not limited to anyspecific form or embodiment, except insofar as such limitations arespecified in the appended claims.

Referring to Fig. 1, when the machine is employed in the customarymanner, that is to say, to produce a single slug from each composedline, the matrices are released from their storage magazine (not shown)and the spacers from their storage magazine A by a keyboard mechanism(not shown), and are delivered to and composed manually elevated toraise the composed line between the fingers c and c of the line deliveryslide C, which thereupon transfers the line from the assembler throughthe intermediate channel D to the line transporter or first elevator E.The first elevator E then descends to carry the line to the castingmechanism where it is justified and then presented to the face of a moldinto which molten metal is injected by means of a pump plunger F to casta slug against the justified line, after which the slug is trimmed anddelivered to the galley R. The first elevator ascends to its uppermostposition and the line is shifted therefrom by the slide G intothe uppertransfer channel G from which the spacers are returned to their mag- 15the main shaft.

azine A and the matrices raised by the second elevator G and deliveredto the distributing mechanism, whereby they are restored to their properchannels in the magazine from which they 5 started.

As is well understood in the art, the various parts referred to, withthe exception of the assembler B which is under manual control, areoperated from the main shaft of the machine,

which is caused to make one complete rotation lever J as is done whenthe line delivery slide C is released, the clutch actuating spring isallowed to engage the clutch and thus start the operation of themachine. The trip dog J is also under manual control, there beingemployed for this purpose, a train of connections leading to the frontof the machine and which comprises in part a vertical sleeve J mountedto turn upon a fixed rod J and which is provided near its upper I endwith a radially extending arm J arranged so in position to engage thetrip dog. By this arrangement, when the sleeve J is manually rotated,the arm J is caused to move the trip dog J clear of the stop lever J sothat the clutch may be engaged in the manner above stated. The de--tails of the clutch control mechanism are fully shown and described inthe Rogers Patent -No. 661,386, and being so well known they do notrequire any further description here.

To complete the identification of the known "parts, it maybe added thatthe main shaft is also provided with a cam F (see Fig. 5) which isshaped to control the operation of the pump plunger F during eachmachine cycle, this cam being arranged to act upon a pivoted lever Fconnected to the pump plunger, and which is connected in turn to thesecond longer lever F which is constantly urged downward to effect thepumping stroke by an attached spring F. In this way,

. .and as also well known; the pump plunger is given one reciprocationat each cycle of operation of the'machine, its down stroke, as effectedby the spring F forcing metal into the mold for the casting of the slug,and its upward stroke, as ef- 1 ,fected by the cam F being its return orinactive stroke.

The parts so far described, and their normal mode of operation incasting single slugs, in themselves constitute no part of the presentinvention, and are or may be of any suitable construction, such forinstance as disclosed in the previouslymentioned Letters Patent No.436,532, or as presented in the commercial linotype machine.

As already stated, the improved equipment is sljintended to adapt themachine automatically to cast duplicate slugs from each of the composedlines when desired, to this end, there are employed means, which may becalled into action at will for actuation by the operation of the metalpump 7 0' plunger F, whereby the transfer slide G is permitted tooperate only at alternate ascents of the first elevator E, the linedelivery slide C is prevented from transferring a new line to the firstelevator until the preceding line has been rei moved therefrom, and theclutch-control dog J is rendered inoperative so as to prevent themachine from stopping at the end of the first cycle of operation,thereby permitting the composed line to be returned a second time to thecasting mechanism.

Reference will be made first to the means employed for controlling theoperation of the transfer slide G. As shown in several of the figures,the transfer slide G is normally locked against operation by a latch O,which is pivoted to the machine frame as at O and which is provided witha nose or shoulder 0 arranged in engagement with a pin 0 projectingforwardly from the transfer slide. At one side of the pivot 0 the latchO is provided with a forward projecting pin 0 which is arranged inposition to be engaged by the head of the first elevator E in itsupward'movement. If the first elevator E makes a full ascent in risingto its line removing position, it engages the projecting pin 0 and liftsthe latch 0 clear of the pin 0 so as to permit the transfer slide toremove the composed line from the first elevator, as intended. If,however, the first elevator fails to rise to its full extent, it willfail to engage the pin 0 or to lift the latch 0 clear of the pin 0 andthereby leave the transfer slide locked against way that the removal ofthe line is preventedand permitted at alternate operations of themachine.

The means referred to, in the embodiment herein illustrated, comprise astop piece P attached to the lower end of the forward arm of a U-shapedbail P pivoted at P to an upstanding support P mounted on the machineframe. Consequently, when the bail P is rocked upwardly, the stop P willbe located in an inactive position or out of engaging relation to thefirst elevator which, therefore, will be allowed to make a full ascent(see Fig. 3); whereas, when the bail P is moved downwardly, it willlocate the stop piece P in its active position or in engaging relationto the first elevator E so as to arrest the latter in its upwardmovement and thereby prevent its complete ascent (see Fig. l). The

operating connections for the bail P will be de-- scribed at a laterpoint.

Reference will next be made to the means provided for locking the linedelivery slide C against movement. As shown in Figs. 1, 2, and 6, thesemeans comprise essentially a long looking lever T, which is arranged inthe guideway wherein the line delivery slide 0 is mounted toreciprocate. The lever T, at its extreme left,

is made fast to a shaft T journaled in a sup-* porting block T attachedto the machine frame, and at its rear end the shaft T is provided with adepending twisted arm T which is connected to the pump plunger F by asystem of levers later to be described. Normally, the locking leverT-will occupy its inactive position as shown in Fig. 2, where it will beseen that the free endofthe lever is held, against the pressure of aleaf'spring'T below or out of the path of movement of the line deliveryslide C, thus permitting the transfer of the composed line from theassembler, B to the first elevator E. Such is the relation of the partswhen a composed line. is forwarded for the first casting operation.After this first casting operation, however, and due to the operation ofthe pump plunger F,- the locking lever T is moved to its activeposition,

as shown in Fig. 1, where it will be seen that,

thefree end of the lever isadapted to engage the block C of the linedelivery carriage and thereby prevent the movement of the. carriage tothe left for the transfer of a newly composed line tothe first elevatorfor the second slug casting operation. It is only after this second slugcasting operation has been effected that the locking lever T, by thesecond actuation of the pump plunger F, is moved out of the way topermit the transfer of the newly composed line to the first elevator.

Reference is now made to the means provided for causing the machine tocarry out the second casting operation automatically. In the presentinstance, and as best shown in Figs. 3, 4, and 5,

there is associated with the actuating arm J 5 for the trip dog J, arightangularly disposed cam H made fast to the rear end of a shaft Hjournaled in the depending arm of a supporting bracket H the latterbeing attached fixedly to the supporting rod J on which the arm carryingsleeve J 3 is mounted to turn. Normally, the high point H of the cam Hoccupies the inactive position shown in Fig. 3, i. e. out of engagementwith the arm J but when the cam is rotated clockwise, its high point .His brought into engagement with the arm J and the latter is rockedtoward the left to move the trip dog J clear of the stop lever J so asto bring about the engagement of the main clutch. The cam H is moved tothis active position by the operation of the pump plunger F in carryingout the first slug casting operation, and hence when the trip dog J iscarried around to its starting position by the rotation of the mainshaft, the arm J will prevent it from engaging the stop lever J and thusleave the clutch engaged to cause a second rotation of the main shaftand consequently a second casting operation. The operation of the pumpplunger F in performing the sec ond casting operation, however, willmove the cam I-I- counterclockwise to its inactive position as shown inFig. 3, so that on this occasion, when the stop dog J is brought-againto its startingposition, it will be allowed to engage and-depress thestop lever J and thereby disengage the clutch to arrest the machine asnormally.

The connectionsfrom the pump plunger F to the several parts which areoperated therefrom will now, be described. As best shown in Figs. 2 and5, there is located in the immediate vicinity of the pump plunger F afour-arm star wheel S, which has fast thereto aneight-tooth ratchet discS The star wheel, with its ratchet, is rotatably mounted upon anenlarged hub portions of a rod or bolt S attached to a supportingv plateL mounted upon the machineframe. The rod or bolt S is extendedtotheleft, as clearly shown in Fig. 7, and has rotatably mounted thereon atoothed actuating disc S for engagement with the ratchet S A compressionspring S also carried by the bolt S acts constantly to maintain theactuatingdisc S in engagement with the ratchet S ,.but willpermit theactuating disc to yield latorally upon the bolt S y/hen: turned in acounterclockwise direction on its inactive stroke. The.

turni g-of, the disc. e :in a ,clockwise .direction,

which isv its active stroke, will advance. the ratchet,

S one tooth forward and impart a similar rotation tothe star wheel S.Briefly stated, thearrangement is suchthat, at each operationofthe;

toothed disc 8 the ratchet S will be advanced;

one-eighth of a rotation and thereby advance-the star wheel S one-eighthof a rotation, the latter acting at successive advances through twotrains.

of connections al ernately to render the line removing means, the linedelivering means and-that machine stopping means inoperative andopera,--

tive, respectively, whereby the machine will operate automatically tocast duplicate slugs from,

the consecutive composed lines.

The ratchet S is connected to the pump-lever F by means of a U-shapedbail F one end, of:

which is securedto the lever F by a clamp con-.

nection F The other end of the bail F adjacent;

the star wheel S, is formed with a hollow boss F in which there isprovided a manually retractable spring detent F which servesas a meansfor connecting and disconnecting the bail F to'and:

from the actuating disc S the-latter being provided with an operatingarm S adapted to be engaged by the detent F and. which is formed with aslot or opening S to permit a certain amount of lost motion.

The star wheel S, which controls'the setting of the first elevator stopP, the line delivery slide stop T, and the clutch control dogdisengaging cam H, is connected with these three elements through twomain trains of connections as 2.1

ready stated.

The connections between the star wheel S and the cam H consist of alever H pivotally mounted on the bracket L, a right angularlydisposedbellcrank lever H mountedon a shaft H journaled' 1n the bracketH and a link H which connectsthese two levers. The lever H is providedat its free end with a roller H adapted to ride on the periphery of thestar wheel S, and which is held in engagement therewith by a spring Hpulling upwardly on the lever H The lever H at its;

free end, is forked or bifurcated and engages with a pin H projectingforwardly from the side of the cam 5. By this arrangement, at successiveH alternately in opposite directions, whereby the clutch control dog Jis governed in the manner:

before described.

The other train of connections consists. of a lever M, pivotally mountedon a forwardly extending arm L of the bracket L, and a right angularlydisposed bell-crank lever M pivotally mounted on an angular extension Lof the bracket arm L The lever M is provided at its:

free end with a roller M adapted to, rideon the periphery of the starwheel S in the same manner as the roller H of the lever H it being heldinengagement therewith by a spring M connected to one arm of thebell-crank M and to the ex tension L of the bracket L. At one end, thebellcrank lever M is forked or bifurcated (like thelever H and engagesthe end ofthelever (see Fig. 3), a certain amount of play thus beingallowed between theselevers in operation.

as the levers M and M are rockedabout their pivots during the rotationof the star wheel S, the stops P and T are both moved into and out ofactive position alternately in the manner before described.

Referring now to the improved galley, it is provided with a plurality ofcompartments for hold-- ing the slugs in separate columns, in order thatthe duplicate slugs may be kept apart and thus obviate the necessity ofsorting them out by hand later on. In the present embodiment, andreferring particularly to Fig. 8, the inclined galley R is divided intoupper and lower compartments R and R respectively, into which the slugsare selectively delivered as they are ejected from the mold and in whichthey are progressively advanced by a stacking device R The inclinedchute N, down which the ejected slugs pass to the galley, is providedwith a guide N fastened to the machine by a suitable hinge n, whichforms the right-hand side wall of the chute and which extends forwardly,as at N into the galley R. Another guide N is pivotally attached to thelower end of the left-hand side wall of the chute, and is connected toand spaced apart from the guide N by a bent link or rod N whereby theswinging of one guide about its pivot will bring about a correspondingmovement of the other.

The connecting link N is rigidly secured to the left-hand guide N buthas a sliding engagement with theright-hand guide N being disposedbetween the outer face of the right-hand guide and a bracket N securedthereto, thus enabling the two guides to partake of a differentialswinging movement resulting from the diiference in location of theirrespective pivots. At this point it may be well to note that thedifferential movement is utilized to contract the space between the twoguides when they are adjusted to direct the slugs into the lowercompartment R the shorter guide N being caused to approach the longerguide N and thus act to deflect the slugs, as they pass between theguides, toward the right and away from the end of the upper flange orshelf B In order that the guides may normally be held in a position todirect the slugs into the upper compartment R the bracket N is providedwith a depending portion N adapted to be held between the galleysupporting bracket R and a raised 1 rib N formed on a resilient member Nsecured to the bracket R the engagement, however, being such that verylittle force is necessary to move the member N over the rib N when theguide plates N and N are swung from one position to another.

The operation of the chute guides N and N is effected by a plunger V,which passes beneath the guides and which is provided at one end with anupright pin V arranged to project through'a ringlet N secured to thebracket N on the outer face of the guide N The other end of the plungerV is in the form of a cam V adapted to be engaged by a roller Vjournaled in the bifurcated end of an extended bolt V which replaces thebolt ordinarily used to secure the upper end of the link V connectingthe first elevator E to its actuating lever. the head of the stackingdevice R and is arranged to engage the outer face of the lower end ofthe guide N so that when the guides are moved to the right to direct aslug into the lower compart ment, the stacking device R is alsocarried'to the right out of the path of the slug. This pin or A pin orlug R projects from guides to their normal positions afterthe trashporter Edescends from line removing position its upward movement by thestop P, the roller V fails to engage the cam V and thus allows theguides N and N to remain in their position to the left, to which theyhave, in the meantime, been returned by the active stroke of thestacking device R Under such conditions, the slugs will be deliveredinto the upper compartment R being arrested by the upper flange or shelfR which extends far enough to the right to intercept the slugs at thetime. The stacking device R is slotted at R to clear this upper flangeor shelf B In the operation of the machine, when it is desired to castduplicate slugs, the detent F is set to connect the star wheel S to thepump actuating lever F The first composed line is then delivered to thefirst elevator and the machine started in the ordinary manner. When thepump actuating lever F is moved downwardly to inject molten metal intothe'mold for the casting of the first slug, the ratchet actuating disc Sis moved in a counterclockwise direction in its idle stroke to pick upone tooth on the ratchet S and as the lever F is raised to itsnorrn'alposition by the rotating cam F on the main shaft, the actuating disc Sis turned in a clockwise direction one-eighth of a rotation, therebyadvancing the star. wheel S one-eighth of a turn.

This fractional rotation of the star wheel S causes the rollers H and Mof the levers H and M, respectively, to come to rest in the depressionss. Thereupon, the upward pull of the spring H on the lever H causes thelatter to rock about its pivot, exerting a downward pressure on theconnecting link H whereby the bell-crank H is rocked about its pivot andthe cam H rotated in a clockwise direction to bring its high point Hinto engagement with the clutch control trip dog actuating arm J At thesame time, the movement of the roller M into its depression (the oneopposite from that of the roller H permits the pull of the spring M torock the bellcrank M in a counterclockwise direction, thereby exerting adownward pull on the rod M to bring the elevator stop P into activeposition, and

releasing the pressure of the rod M on the arm T so that the leaf springT may act to raise the As a'result, the line delivery slide C isprevented (bythe locking lever T) from delivering a new or secondcomposed line to the first elevator E, the first elevator is prevented(by the stop piece P) from making a full ascent into line removingposition and consequently preventing the removal therefrom of the firstcomposed line, and the actuating arm J is cammed into active position totrip the clutch control dog J at the end of the first cycle of operationand thereby cause the machine to continue through a second cycle ofoperation.

When the first composed line is presented a scribed.

second time to the mold, and the pump lever F is actuated to injectmolten metal thereinto for the casting of the duplicate slug, theratchet actuating disc 8* is again operated to advance the star wheel 5through another one-eighth rotation to cause the rollers H and M to rideup onto the peaks 5 of the star wheel arms. This further fractionalrotation of the star wheel rocks the levers H and M against the tensionof their springs H and M in directions contrary to those abovedescribed, causing a counterclockwise rotation of the cam H to disengageits high point H from the clutch control trip dog actuating arm J and aclockwise rotation of the bell-crank M to move the rod M upwardly andcarry the elevator stop piece P out of active position, and to move theother rod M downwardly and swing the stop lever T downwardly against thepressure of the leaf spring T out of the path of the line delivery slideC.

As a result of this alternate operation of the parts, the first elevatorE is permitted to make a complete ascent for the removal of the firstline therefrom, the line delivery carriage C is unlocked and permittedtotransfer into the first elevator the second or newly composed line,and the trip dog J is unaffected by the cam H and allowed to stop the(being its second) operation of the machine.

The continued fractional rotations of the star wheel S puts the partsthrough the same operacessive line until the recasting attachment isrendered inoperative by manually retracting the spring detent F Theoperation of the mechanism for delivering successively cast slug-s todifferent compartments in the galley has already been sufficiently deito the mold, an assembler wherein the line is composed, means fortransferring the composed line from the assembler to the transporter,and automatic means for locking the line transfer means against actionuntil the machine "has-completed several cycles of operation, saidlocking means acting directly on the transfer means and independently ofthe assembler.
